Hello - Question about possible trip:
(All flights on single PNR).
Arrive ORD by UA Domestic mainline; Conneting time 3 hours.
Depart to ZRH with Swiss Air.
In this case, do we have to exit the UA terminal, take the train and re-clear security in the international Terminal (T5?)?
It seems that the inter-terminal airside transfer bus is not operating at this moment.
